The brief
- Planning a 750,000 t/yr smelter in Inola, Oklahoma with Century Aluminum (60/40), the first new US smelter since 1980.
- Its 10th-generation EX cells are larger and run at higher current, for up to 22% more output than its DX+ Ultra cells.
- Says it has cut electricity per tonne of aluminium by 37.5% since 1990.
Technical approach
Own cell design
EX reduction cells
Bigger cells with higher amperage and current efficiency. Two variants: one for output, one for lower energy and emissions; 10 pilot cells at Al Taweelah.
